Be it lcnownthat l, Harrow V. Cons, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented new and useful Improvement in lil eatllis tributers for Cooking-Compartinents5 and I do hereby declare the following; when taken iii-connection with the accompanying drawings and the characters of reference marked thereon, to be a .full, clear, and exact description of the same, and which said din/wings constitute part of this application, and represent, in

Figure 1 a view in front elevation of a cooking compartment of the type in which my improved heat-distributer is preferably used. Fig. 2 view of the compartment in vertical central longitudinal section. Fig. 3 a view in vertical central transverse sec-' tion, from front to rear. Fig; 4 a detached plan view of the 'distributer. Fig. 5 a detachedview of the distributer in rear elevav tion on a reduced scale. Fig. 6 a correspond ing view of the distributer in side elevation. Fig. 7 a detached reverse plan view of the bathe-plate showingits lower face provided with an equalizer.

My invention relates to an improvement in heat-distributors for quasi tireless cook- Q ing apparatus of thetype having ingress and egress draft passages, the object being to provide for the equalization of. the heat throughout the cooking compartment.

' With these ends in view my invention 0011-.

described and pointed out in the claim.

As herein shown, my improved heat-distributer is rectangular in form and adapted to perform the secondary oflice of a rack for food-trays. However, it is not essential to my invention that the device shall be adapted to perform the function of a rack for. food-trays. As shown, the device consists of a top 2,21. back 3 and sides l, being entirely open at the front. In dimensions it is adapted in size to be set in spaced relation within a rectangular cooking compartment 5 having double walls filled as usual with insulating material, the frontof the cornpartment beiiig closed by a double-walled insulated door 6 hung on hinges '7, furnished with a heat-indicator 8 and having a handie 9, The said distribut r is made .sutliciently smaller than the said compartment to form a draft space 10 at each side of it,

a draft space ill 12 back of formed lietsviein open front of the distributor and the inner face of the door 5 of the cooking compartment 5 in which the distrilniter is positioned by means ofoutward ly turned flanges .l-l at the lower ends of itssides dand back Preferably the distributer is made removable from the coinpartment though this is not essential. The bottom of the distributer is formed by a shore it. anda 'draft space removable, solid or 'imperforate baffle-plate 15 supported along its side edges by inwardly extending horizontal ledges 16 it draft space 13 is alsov formed within the; lower ends of the sides lot the distributer. At a point below the plane of the said batlie 'ilate 15 .the back 3 of the distributor is formed with a horizontal series of ports 17 through which a portion of the heated air is deflected bythe bafiie-plate 15" into the rear space 12. in which the heated air is diffused over the said back 3. At a point below the plane of the bathe-plate 15, the sides dot the distributer are formed with corresponding ports 1&-

which, as showmcxtend rearward from the center of the said sides 41 A portion of the heated air is deflected by the loaflle-plate 15 through the ports 18 into the side spaces 10 in which it is diffused over the sides 4 and in which it rises over the top 2 of the distributer into the top air space 11. The said "top 2 of the distributer is-formed with a plurality of ports 19 fro'm which the heated air entering the inside-of the distributor from the front space 13, escapes into the top space 11 above the same. All of the diffused currents into which the heated air is thus broken find their wayultimately to and pass out through the egress draft-passage 20 which is furnished with a damper 21- aerated as occasion may require by the lifting rod 22 actuated by means forming no part of my presentinvention. Heated. air is introduced into the compartment 5 at a point centrally below the bathe-plate 15, through an ingress draft-passage 23 formed in the bottom of the compartment. As shown a gas-burner 2% located directlv below the passage is supplied with gas through a mixing pipe 25. However nW improved dis trihuter works equally well whether used in cooking compartments heated lIVQ'ZlS or oil. As herein shown, Iempioy a heat-com v server. 26 mounted in a frame 2?, whereby compartment-5 and the baffle-plate and receivin hea'ted air through the inlet-pasa space 28 is formed below the heat-conserver for the passage of the heated air laterally into a distributing chamber or space 29 located between the bottom of the i sage V 23 aforesald.

' As shown, my improved distributor is designed to perform the additional function of a rack for supporting food-trays or foodvertical series of inwardly projecting oppositely located horizontal ledges 30. V

'In'the use of a cooking compartment having an ingress draft-passage and an egress draft-"passage, the natural tendency is for a the heated air to'take the shortest course be tween the two passages, resulting in the Stratification of the heat in layers varying widely in temperature and detrimental to the; cooking operation which is best carried on when the heat is the same in every part of the compartment. The amount of heated air passing through the respective ports and passages described is regulated by the; size and numbe'r of ports and the size of the passages, all of which may be predetermined so that the heated air enveloping the distrib tor will be substantially equalized'in tern: perature and speed of movement. The efiect of my improved distributer is to equally heat all parts of the space reserved within the cooking compartment for the reception of the food.

. As shown in Figs. 3 7 the baflie-plate .15 is provided upon the center of its vlower face with a rectangular equalizer 31 pyramidal in its form' in so far as it tapers in each direction from its'center. The application I or thig equalizer to the bottom r the bafileplate forms a chamber 32 which is filled with suitable insulating material, such as asbestos. The particular value of the construction just described lies in the use of the apparatus without the heat-conseTver when the heat I rises directly. against the bafiie-plate which,

in ithe absence of the equalizer, .would be superheated at its'center, endangering the burning of thecontents of the cooking com- I partment. Obviously a conical equalizer might replace the rectangular pyramidal equalizer 31, this depending on the shape of the cooking-compartment.

My improved device'l's not limited to'use for cooking purposes, but might also. be used i I for drying japanned articles, and in carrying on any other processes requi-rmg heating and drying;
